2 Input current at external contact ON
9mA or more
3 Input voltage at external contact OFF
20V or more, 25.2V or less
4V or less
4 Input current at external contact OFF
2mA or less
5 Tolerable chattering time
3ms or less (Refer to T1 below)
6 Input signal holding time
40ms or more (Refer to T2 below)
7 Input circuit operation delay time
